Java实现两人五子棋游戏(二) 画出棋盘

本文为大家分享了java画出五子棋游戏棋盘的方法，供大家参考，具体内容如下

棋盘模块：

画五子棋棋盘：19条横线、19条竖线

步骤一：显示棋盘

我有一张名为chessboard.png的棋盘，位置为根目录/res/drawable/chessboard/png，现在我要显示这张图片。

drawchessboard.java

package xchen.test.simplegobang; 
 
import java.awt.graphics; 
import java.awt.image; 
import java.awt.toolkit; 
 
import javax.swing.jpanel; 
public class drawchessboard extends jpanel{ 
 public image boardimg; 
 public drawchessboard() { 
 boardimg = toolkit.getdefaulttoolkit().getimage("res/drawable/chessboard.png"); 
 if(boardimg == null) 
  system.err.println("png do not exist"); 
 } 
 @override 
 protected void paintcomponent(graphics g) { 
 // todo auto-generated method stub 
 super.paintcomponent(g); 
  
 int imgwidth = boardimg.getwidth(this); 
 int imgheight = boardimg.getheight(this); 
 int fwidth = getwidth(); 
 int fheight= getheight(); 
  
 int x=(fwidth-imgwidth)/2; 
 int y=(fheight-imgheight)/2; 
 g.drawimage(boardimg, x, y, null); 
 } 
} 

main.java

package xchen.test.simplegobang; 
 
import java.awt.container; 
import javax.swing.jframe; 
 
import xchen.test.simplegobang.drawchessboard; 
 
public class main extends jframe{ 
 private drawchessboard drawchessboard; 
 public main() { 
 drawchessboard = new drawchessboard(); 
  
 //frame标题 
 settitle("单机五子棋"); 
  
 container containerpane =getcontentpane(); 
 containerpane.add(drawchessboard); 
 } 
 public static void main(string[] args) { 
 main m = new main(); 
 m.setvisible(true); 
 } 
} 

运行一下

步骤二：为棋盘画上横竖线

drawchessboard.java

package xchen.test.simplegobang; 
 
import java.awt.graphics; 
import java.awt.image; 
import java.awt.toolkit; 
 
import javax.swing.jpanel; 
public class drawchessboard extends jpanel{ 
 public image boardimg; 
 final private int rows = 19; 
 public drawchessboard() { 
 boardimg = toolkit.getdefaulttoolkit().getimage("res/drawable/chessboard2.png"); 
 if(boardimg == null) 
  system.err.println("png do not exist"); 
 } 
 @override 
 protected void paintcomponent(graphics g) { 
 // todo auto-generated method stub 
 super.paintcomponent(g); 
  
 int imgwidth = boardimg.getwidth(this); 
 int imgheight = boardimg.getheight(this); 
 int fwidth = getwidth(); 
 int fheight= getheight(); 
  
 int x=(fwidth-imgwidth)/2; 
 int y=(fheight-imgheight)/2; 
 g.drawimage(boardimg, x, y, null); 
  
 int margin = x; 
 int span_x=imgwidth/rows; 
 int span_y=imgheight/rows; 
 //画横线 
 for(int i=0;i<rows;i++) 
 { 
  g.drawline(x, y+i*span_y, fwidth-x,y+i*span_y); 
 } 
 //画竖线 
 for(int i=0;i<rows;i++) 
 { 
  g.drawline(x+i*span_x, y, x+i*span_x,fheight-y); 
 } 
  
 } 
} 

main.java不变
运行一下

遇到的问题：

1）eclipse不识别文件夹下的图片

问题：文件夹中有图片，但是在eclipse项目栏中不显示

解决办法：在eclipse中，选中根目录，f5 refresh，就显示出来了。
